GXL2GV,GV2GXL(1)                                                                                                GXL2GV,GV2GXL(1)



NAME
       gxl2gv,gv2gxl - GXL-GV converters

SYNOPSIS
       gxl2gv [ -gd?  ] [ -ooutfile ] [ files ]
       gv2gxl [ -gd?  ] [ -ooutfile ] [ files ]

DESCRIPTION
       gxl2gv  converts  between graphs represented in GXL and in the GV language. Unless a conversion type is specified using a
       flag, gxl2gv will deduce the type of conversion from the suffix of the input file, a ".gv" (or a ".dot") suffix causing a
       conversion from GV to GXL, and a ".gxl" suffix causing a conversion from GXL to GV.  If no suffix is available, e.g. when
       the input is from a pipe, and no flags are used then gxl2gv assumes the type of the input file from its  executable  name
       so that gxl2gv converts from GXL to GV, and gv2gxl converts from GV to GXL.

       GXL supports a much richer graph model than GV. gxl2gv will attempt to map GXL constructs into the analogous GV construct
       when this is possible. If not,  the  GXL  information  is  stored  as  an  attribute.  The  intention  is  that  applying
       gxl2gv|gv2gxl is semantically equivalent to the identity operator.

OPTIONS
       The following options are supported:

       -g     The  command  name and input file extensions are ignored, the input is taken as a GV file and a GXL file is gener-
              ated.

       -d     The command name and input file extensions are ignored, the input is taken as a GXL file and a GV file  is  gener-
              ated.

       -?     Prints usage information and exits.

       -o outfile
              If specified, the output will be written into the file outfile. Otherwise, output is written to standard out.

OPERANDS
       The following operand is supported:

       files   Names  of  files  containing 1 or more graphs in GXL or GV.  If no files operand is specified, the standard input
               will be used.

RETURN CODES
       Both gxl2gv and gv2gxl return 0 if there were no problems during conversion; and non-zero if any error occurred.

BUGS
       gxl2gv will only convert in one direction even if given multiple files with varying suffixes.

       The conversion can only handle one graph per GXL file.

       There are some GXL constructs which gxl2gv cannot handle.
